Red Dead Redemption held a 4x XP weekend, which I was able to go from level 28 all the way to 50 and unlock a few multi-player related achievements as well. I managed to 1,000 Truth or Lies using the ever-so-popular fan method. I also purchased what I think is my Game-of-the-Year, Child of Eden, which makes the best use of the Kinect sensor to date.
